Dotconf
=======
Dotconf is an advanced configuration parser which allow nested sections to any
level, typed values in syntax, file include and so more. Dotconf is also
shipped with a powerful schema validation system.
The full documentation can be found here: http://dotconf.readthedocs.org

Features
--------
- Configuration format kept as simple as possible.
- Developer friendly APIs.
- Types are expressed in the syntax, so the parser can guess it without
validation.
- Four primitive types: string, number, boolean, or list.
- More complex composite types can be created using the schema validation
system.
- Nested section of any deep. Sections can take a special "argument" value
(look at the example).
- Schema validation system, all schema can be defined using declarative or
imperative way.
- External file include with globbing.
- Integration with argparse.
- Tests (only parser is covered yet)
- Released under MIT license.
Example
-------
This is an example of configuration file for an imaginary web server::
daemon = yes
pidfile = '/var/run/myapp.pid'
interface = '0.0.0.0:80'
interface_ssl = '0.0.0.0:443'
host 'example.org' {
path '/' {
rate_limit = 30
}
}
host 'protected.example.org' {
enable_ssl = yes
path '/files' {
enable_auth = yes
user 'foo' {
password = 'bar'
}
}
}
You can access to each values using the developer friendly API::
>>> from dotconf import Dotconf
>>> parsed_conf = Dotconf.from_filename('mywebserver.conf').parse()
>>> print parsed_conf.get('daemon', False)
True
Even more exciting, you can create a validation schema to avoid you the
painful chore of manual configuration file validation::
from dotconf.schema.containers import many, once
from dotconf.schema.containers import Section, Value
from dotconf.schema.types import Boolean, Integer, Float, String
# Schema definition:
class UserSection(Section):
password = Value(String())
_meta = {'repeat': many, 'unique': True}
class PathSection(Section):
rate_limit = Value(Float(), default=0)
enable_auth = Value(Boolean(), default=False)
user = UserSection()
class VirtualHostSection(Section):
enable_ssl = Value(Boolean(), default=False)
path = PathSection()
_meta = {'repeat': many, 'unique': True}
class MyWebserverConfiguration(Section):
daemon = Value(Boolean(), default=False)
pidfile = Value(String(), default=None)
interface = Value(String(), default='127.0.0.1:80')
interface_ssl = Value(String(), default='127.0.0.1:443')
host = VirtualHostSection()
Then you can use the API exactly as if it was not validated::
>>> conf = '''
... daemon = yes
... pidfile = '/var/run/myapp.pid'
... interface = '0.0.0.0:80'
... interface_ssl = '0.0.0.0:443'
...
... host 'example.org' {
... path '/' {
... rate_limit = 30
... }
... }
...
... host 'protected.example.org' {
... enable_ssl = yes
...
... path '/files' {
... enable_auth = yes
... user 'foo' {
... password = 'bar'
... }
... }
... }
... '''
>>> from dotconf import Dotconf
>>> from myconfschema import MyWebserverConfiguration
>>> parsed_conf = Dotconf(conf, schema=MyWebserverConfiguration()).parse()
>>> print 'daemon:', parsed_conf.get('daemon')
daemon: True
>>> for vhost in parsed_conf.subsections('host'):
>>> print vhost.args
>>> if vhost.get('enable_ssl'):
>>> print ' SSL enabled'
>>> for path in vhost.subsections('path'):
>>> print ' ' + path.args
>>> if path.get('enable_auth'):
>>> print ' Following users can access to this directory:'
>>> for user in path.subsections('user'):
>>> print ' - ' + user.args
>>>
example.org
/
protected.example.org
SSL enabled
/files
Following users can access to this directory:
- foo
Setup
-----
The fastest and more common way to install Dotconf is using pip::
pip install dotconf
Debian
~~~~~~
If you use Debian, you can also use the Tecknet repositories. Add this lines
in your ``/etc/apt/source.list`` file::
deb http://debian.tecknet.org/debian squeeze tecknet
deb-src http://debian.tecknet.org/debian squeeze tecknet
Add the Tecknet repositories key in your keyring:
# wget http://debian.tecknet.org/debian/public.key -O - | apt-key add -
Then, update and install::
# aptitude update
# aptitude install python-dotconf
Archlinux
~~~~~~~~~
If you use Archlinux, a Dotconf package is available in Aur::
yaourt -S python2-dotconf

- More test.

- Fixed an error when a section is included by an external file (thanks to
DuanmuChun for its bug report and help to fix it)
- Fixed other minor bugs

you want to package it for your distro.
Changes:
- Added Eval, NamedRegex and RegexPattern types
- Added TypedArray container
- Fixed bug with scalar values from a singleton list in Value container

A note on versioning
--------------------
Dotconf use a two numbers X.Y versioning. The Y part is incremented by one on
each release. The X part is used as API compatibility indicator and will be
incremented each time the API is broken.
